Dwyer PRV - Manual

PRV Series Pneumatic Roller Vibrators
• Special aluminum body is small in size and light-weight.
• Frequency and amplitude of vibration can be adjusted as required.
• The strongest vibration force driven by rollers among the same size
products.
Series PRV Pneumatic roller vibrators have a high vibration frequency
feature that can prevent material jams in pipe delivery. It can also be
applied for bridge-break or concrete injection operation conditions.
HOW IT OPERATES
The special aluminum body is equipped with a roller and ring with multi-
nozzles. It is tightly closed by plastic side covers. Vibration is caused
when the roller pushed by compressed air runs in a rotary motion to
produce centrifugal force.

INSTALLATION
Vibration force transmits more efficiently in a conical hopper tank as
opposed to a rectangular hopper. It is recommended that you install two
vibrators in rectangular hoppers.
1. Vibrator force can be transmitted more efficiently by using “U” shape
steel supports. It can help materials run smoother in the tank or pipe. It
also reduces tank damage accidents.
2. To avoid tank wall amplitude caused by the vibrator moving in a left
or right direction, use “U” shape steel.
3. Reinforced board is required between “U” shape steel and a thin tank
wall.
4. To increase vibration fields in a big hopper tank, criss-cross “U” shape
steel.
